Answer to Question #54553 in Genetics for Misha Jain

Question

What is the probability of three daughters to a couple in three children and how?
(1) 1/4
(2) 1/8
(3) 1/16
(4) 3/8

Answer 1

The probability of daughter in each separate case is 1/2 because the probabilities of boy and girl are equal.
Thus, the probability of three daughters is a product of probabilities of daughter in each case:
1/2 *1/2 *1/2 = 1/8
